Goblin snakes combine elements of both goblin and serpent into a single, repellent whole. Though some speculate these creatures may be a form of lesser naga, goblins themselves revere these aberrations as racial heroes of the past, reincarnated into a new form in order to deliver retribution to the enemies of their kind.

Appearance:

The most striking feature of a goblin snake is its head, which resembles that of a reptilian goblin. Their wide mouths are filled with jagged teeth and fangs, and their tongue is forked similar to that of a snake. They view the world through the white eyes of a serpent, and their broad ears sweep back along their skull.

Goblin snakes can reach lengths of up to 6 feet, and their bodies are covered in black scales with a thin red stripe down both flanks. These creatures possess a series of dorsal spikes that are present the entire length of their bodies.

I get it, it's not a goblin. In a game with several errata, one of which is specifically not having the word goblin on a card, I don't think it was much of a leap to think that could be the case here as well.

And I suppose it isn't a goblin, but it has a goblin face and is inherently goblin like. As stated above, the goblin snake combines the features of a goblin and a snake into a single entity. It isn't just a snake used by goblin's, but instead has goblin features. So saying that this goblin snake might be a goblin isn't entirely ridiculous. I'm just watching out for errata in a game where there has been a large quantity already found.
